IMPROVEMENT IN SKATES.

TO A'LLWHOM 'IT MAY CONCERN:

Beit known that I, AUHILLE FQMIGEON, ot: Wolcottville, in thecounty 'of Litchfield, and State of Connecticut, havo invented, made, and applied to use, a certain nexviand usefullmprovemcnt in Skates; and I do hereby 'declare the following to be a full, clear, and exact description of the said invention, reference being had to thel annexed drawing, making part of this speciic'ation, wherein4 i v Fignre 1 is an invertedpla'n of said skate. i

Figure?l is a side view of the same. u FignreB is aa cross-section at the line x x; and

Figure 4 is a separate view' of the double bracket that unites the runner'to theplate. Similar parts are referred to by like letters: u Skates have .heretofore been made with-'the soleand heel-plates united directly to the upper ends ofwarms y formed en thc runners, bntfit'is found in useithat-theleverag'e and strain "usethe parts to `worlrloose and give out when thus riveted together. v'.lfoobviate this difficulty, the arms of the runner have been united to the sole and heel-plates by pairs of angle-irons, riveted to the respective parts.- These, however, are unsightly, and do not allow of the plates being removed lfrom the runner to facilitate the grinding and polishing of the latter( Skates have also beenmade withclamps for the sides ofthe sole of the boo-t, said clamps, in-some instances, j being made separate, and adjusted by screw-bolts in ,slots in the sole-plate. In other instances the clamps have L been drawn together by a bolt, passing through flanges turned up at the' ends of the clamps. In the'rstnamed character of'clamp, but little compressing power can be obtainedupon the sides of the boot-sole. In the last-named character of clamp the sole may be grasped firmly, but there is nothing to prevent the sole-plate and skate slipping crosswise beneath the'sole of'the boot, particularly in cases where the boot-sole is considerably wider than the metallic sole-plate. I i i The nature of my said invention consists- First, in a double bracket, of metal, setting across the upper end of each ofthe arms of tllc runner, and united by the endof thel arm. passing through an opening in the bracket,land beingriveted. The ends ofthe brackets arc attached to the sole and heel-plates, respectively, by'screns.' This device is very strong and handsome, and allowsl the runner to be disconnected-for grinding or polishing. i i

Second, n` a pair of clamps, one of Awhich is adjustable and clamped rmly by abo lt.` The other is operlated upon by a screw, that passes through one of the arms of the skate-runner. By this construction the skate can-beadapltcd to various widths oi' boot-soles, and the clamping-operation will bervery rm and reliable, and there is no opportunity for the skate itself to move laterally beneath the boot-sole.'

In the drawing, ci is the runner, formed with the arms or upward projections 6 c d extending to the under, side ot' the sole-plate e and heel-plate f. l ,y

The double bracketsgl are each formed with an opening in 'the middle, as seen in iig. 4, into which-a tongue, at the end of the arm of4 the skate, projects, and is'riveted firmly, as seen at z'. The thickness of thefbracket is such thatrthe parts are held irmlygand cannot wvorlcloose, and the screws at o, connecting the end-portions -of the double bracketsv to the plates, render the attachment very secure.` I prefer to employthe screws o, but

rivets might be used, it` desired. i

The clamps 7c and Z are applied. to the sole-plate e. .The clamp lc is attached by a bolt, p, passing'tbrough a slot in the said plate e, so that' it may be placed and secured in any desired position, according to the width oi' the solo of' the boot. n

The clamp YZ is held to/theplate e bya bolt,- s, but not clamped tightly, and the screw m passes through the flange or angle atlthe inner endof the clamp l, into the-arm c of the skatefrunner, the holle in which has a thread cut in it' for the Screw m, softhat the rotation of said screw firmly clamps the shoe or boot-sole, or-

releases the hold upon the same, andn there is no opportnity for the skate itself to move laterally beneath the boot or upon the clamps.

The arm c is made Wider than generally heretofore usuahan order that une screw m may be introduced in` the same at the p'roper place for acting upon the clamp l.

What I claim, and desire to secure by Letters Patent, is-

1. The metallic brackets g g, each formed with en elongated hole receiving the tongue nt the 'end of the runner-erm, into which said. tongue is riveted, so-that said brackets yStand as Tpieces across Athe :i1-ms ef the runner, and are united to the sole-plate by the screws or rivetso, as set forth. Y

2. The clamps 7e Z, in combination with the screw 71g, that passes through the flange of the clnmp- Z, and through e threaded hole in the runner, tting said screw 7n, so as to confine the boot-sole, by the clamps lc Z, in the manner specified.

In Witness whereof', I have'hereunto set my signature, this sixth dayhf March, A. D, 1868.
